This is my second attempt at a plyo box. This time in technicolor! I took a ShopBot class at TechShop and decided it would work better than the inaccuracies of the table saw and band saw.
3/4" sheet of plywood (I chose a birch variety)
Two-flute end mill (I chose 1/4")
Screws (at least 1.5 in long)
Drill bit (1/8")
Brass screws (long enough to go through material; 1.5")
